Counting incomplete surveys that reach certain Question

Yes this would be incredibly valuable in both survey design and determining what to count as 'complete'. I would add to it a bit as well. The percent complete counts in Qualtrics are total garbage since they count every element in a survey, whether viewed by the recipient or not (e.g. masked by logic/viewable), and whether they are actual questions or instructions/text, which makes it near impossible to get any information about how far along the respondent actually was when they dropped out from the survey. It could be as simple as flag that indicates which elements to include in the completion counts, and making sure that logic trees are accounted for in determining percent complete. Combining that measure along with some indicator of last item completed would improve the existing capability and meet the need described above.

I just add embedded variables at different points in the survey. Then when the responses close, I filter based on "is not empty" and am able to determine who completed how much.
